Furthermore ffmpeg is not copying anything there.  You did not tell
ffmpeg to copy.  It is encoding with (probably rubbish) defaults.

As convenient as "-report" can be I usually do not recommend it because
by default it uses the "verbose" log level which definitely lives up to
its name: it's needlessly too verbose for general help. The verbosity
usually exceeds my laziness threshold and I tend to just move on to a
different question.

The FFREPORT environmental variable can be used instead, but I don't
know if that works with Windows, and it would probably be too confusing
for some users.

No, honestly, it seems to be an issue which only manifests itself with
Premiere Pro. Why not ask there?

Furthermore, "Pro" implies "Professional", which means it was made
either by or for "professionals", i.e. people who earn their living
with this. To make things worse, you probably even paid for that
software, and it likely even advertises H.265 support. I think you
deserve to get an answer from them as to what their requirements are
towards an H.265 file.

Everything else is just guesswork or reverse engineering.

Welcome here anyway, if ffmpeg can help to work around Premiere Pro's
shortcomings. ;) (Not saying it couldn't be an ffmpeg issue. Let's
see.)

Re: [FFmpeg-user] H.265/HEVC for Premiere Pro compatibility

[Chris Colton]

I'll keep -report in mind that's a great option that I didn't know existed.
I just tried converting a different file and Premiere plays it fine. The
source that worked was a H.264 (extremely high bitrate) and the one that
didn't was DNxHR in .MOV so I'll try it again with DNxHR and see what
happens.

Actually, it's easier to either
a) google for how to text copy out of a console, or even
b) use the ffmpeg/ffplay/ffprobe command line option "-report". It will
   nicely place a log file into the current directory which contains
   the command line an the complete, uncut console output - even
   without the line wraps which the Windows cmd console introduces.
   This text file then should be attached to the response on this list.

When all else seems to fail, the "supporters" on this list should
recommend using the latter option and attaching the resulting file.

I don't know–I don't use Windows (I'm guessing that's what you're

redirect the console output to a text file with a search.

[FFmpeg-user] H.265/HEVC for Premiere Pro compatibility

[Chris Colton]

Hi all,

I tried to get an answer on this before I actually subscribed to the
mailing list, so I'm told I didn't receive all the replies so I'm just
starting over here.

I'm using FFmpeg to transcode to H.265 because Premiere's native encoding
is incompatible with Vimeo (Vimeo's transcoding causes a color shift in
HEVC from Premiere). I also love the constant rate factor encoding option
because it'll decide bitrate depending on the resolution needed. I used the
command below and VLC and Vimeo both play it (vimeo with no color issues),
but if you try to check the encode to the original in Premiere, it imports
with sound playing correctly and just a blank green image instead of the
video. Any ideas?

-i "source.mov" -y -c:v libx265 -preset veryfast -crf 23 -vf format=yuv420p
-c:a aac -b:a 320k -ar 48000 -ac 2 -max_muxing_queue_size 1000 "H265.mp4"

Ok, more denoising and small tuning:

-preset veryslow -profile high -b:v 2M -refs 8 -me_range 64 -qcomp 0.7

Could you reencode that better quality sample to include initial intro 
from source you provided?


Btw. I hope you will update your ffmpeg

besides that 2.8.x is *terrible* outdated when we have 3.1 und 3.2 over 
many months - any reason why cut out the command line itself which makes

[FFmpeg-user] Can't get a/v synchronisation right with mpeg transport stream that has gaps in it

[Erik Slagter]

Hi people,

I'm having this problem for years and years (so it's not a recent
problem or regression).

I make recordings on my enigma2 based settopbox. It saves the recordings
as the original transport stream, but with filtering of only the
requested service pids.

There is a feature to edit the recorded services, in a basic way. Very
helpful to edit out commercials. Problem is that it makes cuts in a very
"rude" way, it justs cuts the file at a certain position, in the middle
of all kinds of open packets and streams. On playback it isn't such a
big deal, because the damaged packets are discarded and the DVB hardware
resyncs on the timestamps pretty quickly.

After the crude editing, I like to perform a real editing run, using
kdenlive (or any other NLVE, for that case). I've found that all of them
have problems when fed with a "damaged" transport stream, like this. So
what I do, is transcode the stream to something with mjpeg and pcm
codecs, intra frames only, very easy on the editor.

This is the problem: after every timestamp discontinuity ("cut" or
"gap"), ffmpeg resyncs audio and video BUT it doesn't do it 100%
correctly. Sound remains a bit "in front" of the video, skewed a bit.
Also, it gets worse at every cut, everytime about 200-300 ms is added to
the skew. That's not what I'd expect?

I've tried these options to force synchronisation:

- -vsync 1 (not per sé required, but I want the audio and video streams
in the container in such a way that they're not skewed, so if the editor
decides to demux and throw away the timestamps, it still works)
- -r 25 (material is 25 fps, tried with and without, doesn't matter)
- filter:a "
aresample=async=1:min_comp=0.1:min_hard_comp=0.1:max_soft_comp=1:first_pts=0"

None of this helps. I can see ffmpeg dropping and dupping frames, but it
doesn't help to fix the slow drift.

I was under the impression that ffmpeg would automatically base the
synchronisation of the (single) audio stream on the (single) video
stream. Is this a correct assumption or do I need to specify an explicit
"-map" statement?

It looks like ffmpeg takes care that frames are dupped/dropped so the
frame rate keeps "solid" 25 fps (or whatever the source frame rate is
specified as or is specified with -r), but it seems it does not keep the
audio stream synchronised.

Thanks for help,
Erik.

I've just tested playing back a .mov file and a .wmv file.  The Sept 24th
version (SDL) plays fine. The Sept 26th version (SDL2) does not, only hear
audio.

So, if it's something wrong with my display, is there something I can dload
to get it working, like a library? I'd prefer to use the most current
ffmpeg.

It is supposed to open a playback window (with a generated test
source).

That's not desired.

In this case, the output device's name is "sdl". -> "-f sdl foo".
Please do try that with the old build.

My current analysis, in other words: Something is wrong with the way
SDL2 tries to interact with your display, that's why ffplay doesn't
open a window.

Does ffplay work with anything else than MKV/H.264? (Because that's
what you mentioned originally.)

Hi Moritz, Not sure what I supposed to see but I didn't see anything other
than the command window.  Also the command window did not seem to respond
to 'q'.  I had to ctrl + c three times to force it to stop.

Here's the console output and command for September 26 build

Here's the command and output for 24th build. As you stated in your reply
this was before they changed to sdl2 so the error that occurs makes sense.

Re: [FFmpeg-user] gain the highest quality with H264 at a certain bit rate

[negin tebyani]

unfortunately this does not make differences in results either:

Then i can think only about that:

I'm realy stuck in here, I have tried any commands and any suggestions, but
I'm not even close to that quality (actually I need to be even better than
than one).

Firstly: "It works for me(TM)." I can play that file's video with the
64bit version from Zeranoe.

Interestingly, between those two builds you mention (1212e34..64545dd),
ffplay was switched from using the SDL1 library to SDL2. (Zeranoe
probably didn't have the latter available in their build environment
for a few days, until they noticed.)[*]

Great that you were able to track that down. I don't know how to debug
the SDL display device though.

Does this command show you something on your screen, i.e. does the sdl2
output device work?

$ ffmpeg -re -f lavfi -i testsrc2=s=1366x768:r=30,format=yuv420p -f sdl2 foo

Re: [FFmpeg-user] ffplay on current build does not play mkv file but on old build does.

[Tim Hiles]

Hi All!

I'm revisiting this issue because I've finally had time to narrow down the
exact release where this issue first arose from so that perhaps someone who
understands the code could maybe figure out what may have happened.

From this page: https://ffmpeg.zeranoe.com/builds/win32/static/

Scroll down to here:

  ffmpeg-20160926-64545dd-win32-static.zip

   26-Sep-2016 23:10   41M
  ffmpeg-20160926-69449da-win32-static.zip

   26-Sep-2016 19:09   27M
  ffmpeg-20160924-267da70-win32-static.zip

   24-Sep-2016 22:09   27M
  ffmpeg-20160924-1212e34-win32-static.zip

   23-Sep-2016 22:11   41M

note: keep in mind that the list of releases above is in descending
chronological order (newest at the top, oldest at the bottom) exactly as it
is on the zeranoe webpage.

Starting from the old release going up here is what I've discovered..
1. September 23 2016 at 22:11 is the last version that plays video in the
mkv file.
2. September 24 2016 and September 26 2016 you'll notice that the zip
folder size drops down to 27 M. That's because if you download those two
zip folders you'll see that ffplay.exe was not included.
3. Then September 26, 2016 (later that evening) it goes back up to 41M
because it includes ffplay.  From that point on, ffplay no longer plays
mkv's for me, only audio.

So, I'm unsure what happened at that time but that if any developers want
to look into this, this is where I would start my investigation.

Thanks for any help!

Tim

[chronek]

Then i can think only about that:

ffmpeg -y -i in.mp4 -an -c:v libx264 -preset veryslow -b:v 2048k -refs 8 
-qcomp 0.7 -nr 40 -flags +loop -deblock 1:0 -pass 1 /dev/null

out.mp4

The problem is that when I pause both  videos at the same scene, the other
video is so smooth and you can't see any noise, but mine is not like that.
It seems they have used some video filter or something to Remove the noise.
